BOSTON (AP) -- Lawyers for two men charged with conspiring to obstruct justice in the Boston bombing case say their clients had no idea the attack was being planned.

The lawyers for Azamat Tazhayakov and Dias Kadyrbayev held a brief news conference Wednesday after their clients' initial court appearance.

Attorneys Robert Stahl and Harlan Protass say their clients were just as shocked as everyone else and didn't have anything to do with the attack.

They are accused of removing a backpack containing hollowed-out fireworks from suspect Dzhokhar Tsarnaev's dorm room three days after the attack to keep him from getting into trouble.

A third man, Robel Phillipos, is charged with making false statements to federal investigators. He awaits a court appearance.

The three aren't accused of any direct involvement in the bombing. But according to court papers, the FBI said that about a month before the bombing, Tsarnaev told two of them that he knew how to make a bomb._______

BOSTON (AP) -- Two men who attended college with the Boston Marathon suspect and are charged with conspiring to obstruct justice have waived bail.

Azamat Tazhayakov and Dias Kadyrbayev appeared in court Wednesday and agreed to voluntarily detention.

Their next hearing is scheduled for May 14.

A third man, Robel Phillipos, is charged with making false statements to federal investigators. He awaits a court appearance.

An FBI affidavit says the three men removed bombing suspect Dzhokhar Tsarnaev's backpack from his dorm room at the University of Massachusetts at Dartmouth three days after the bombing.________

BOSTON (AP) -- Three more suspects were taken into custody in the Boston Marathon bombing case, including two college friends of Dzhokhar Tsarnaev who came to the U.S. from Kazakhstan, officials said Wednesday.

The allegations against them were not immediately disclosed. Gov. Deval Patrick, who said he was briefed on the investigation, told reporters it's his understanding that the suspects had nothing to do with the bombings but helped the suspect after the fact.

Three people were killed and more than 260 injured on April 15 when two bombs exploded near the finish line. Suspect Tamerlan Tsarnaev died after a gunfight with police several days later. His brother, Dzhokhar Tsarnaev, was captured and lies in a hospital prison.

Linda Cristello, a Boston attorney who represented Azamat Tazhayakov and Dias Kadyrbayev in immigration court Wednesday morning, said her clients now face separate federal charges and have an afternoon court appearance related to the bombing case.

The two have been held in jail for more than a week on allegations that they violated their student visas while attending the University of Massachusetts at Dartmouth with Dzhokhar Tsarnaev.

Christina DiIorio-Sterling, a spokeswoman for U.S. Attorney Carmen Ortiz, told reporters gathered outside federal court that the charges are expected to be unsealed Wednesday afternoon when they make their initial appearance before a magistrate judge.

The identity of the third new suspect wasn't immediately released. A law enforcement official briefed on the investigation but not authorized to talk about it told The Associated Press on the condition of anonymity that it was a man.

Tamerlan Tsarnaev's relatives will claim his body now that his wife has agreed to release it, an uncle said. Tsarnaev, 26, has been at the medical examiner's office in Massachusetts since he died after a gunfight with authorities more than a week ago.

Amato DeLuca, the Rhode Island attorney for his widow, Katherine Russell, said Tuesday that his client had just learned that the medical examiner was ready to release Tsarnaev's body and that she wants it released to his side of the family.

Police said Tsarnaev ran out of ammunition before his 19-year-old brother dragged his body under a vehicle while fleeing the scene. His cause of death has been determined but will not be made public until his remains are claimed.

"Of course, family members will take possession of the body," uncle Ruslan Tsarni of Maryland said Tuesday night. "We'll do it. We will do it. A family is a family."

He would not elaborate. Tsarnaev's parents are still in Russia, but he has other relatives on his side of the family in the U.S., including Tsarni.

Tsarnaev's father, Anzor, announced plans last week to travel to the U.S. in the hope of burying his elder son, but he told the AP on Wednesday that those plans are off because he is suffering from bad headaches and high blood pressure. The 46-year-old Tsarnaev said he still hopes to go when he is feeling better.

Dzhokhar was wounded in the shootout with police as he and his brother made their getaway attempt. He is charged with using a weapon of mass destruction to kill, a crime that carries a potential death sentence.

Russian agents placed the older suspect under surveillance during a six-month visit to southern Russia last year, then scrambled to find him when he suddenly disappeared after police killed a Canadian jihadist, a security official told the AP.

U.S. law enforcement officials have been trying to determine whether Tamerlan Tsarnaev was indoctrinated or trained by militants during his visit to Dagestan, a Caspian Sea province that has become the center of a simmering Islamic insurgency.

The security official with the Anti-Extremism Center, a federal agency under Russia's Interior Ministry, confirmed the Russians shared their concerns. He said that Russian agents were watching Tsarnaev, and that they searched for him when he disappeared two days after the July 2012 death of the Canadian man, who had joined the Islamic insurgency in the region. The official spoke only on condition of anonymity because he was not authorized to speak to the news media.

Security officials suspected ties between Tsarnaev and the Canadian - an ethnic Russian named William Plotnikov - according to the Novaya Gazeta newspaper, which is known for its independence and investigative reporting and cited an unnamed official with the Anti-Extremism Center, which tracks militants. The newspaper said the men had social networking ties that brought Tsarnaev to the attention of Russian security services for the first time in late 2010.

President Barack Obama said Tuesday at a news conference that the U.S. counterterrorism bureaucracy "did what it was supposed to be doing" before the Boston Marathon bombing as his top intelligence official began a review into whether sensitive information was adequately shared and whether the U.S. government could have disrupted the attack.

"We want to go back and we want to review every step that was taken," Obama said. "We want to leave no stone unturned. We want to see, is there in fact additional protocols and procedures that could be put in place that would further improve and enhance our ability to detect a potential attack."

In Rhode Island, DeLuca said Tamerlan Tsarnaev's widow met with law enforcement "for many hours over the past week" and will continue cooperating. FBI agents on Monday visited her parents' North Kingstown, R.I., home, where she has been staying, and carried away several bags.

"Katherine and her family continue to be deeply saddened by the harm that has been caused," DeLuca said Tuesday.

Terrel Harris, a spokesman for the Department of Public Safety, said Tuesday evening that the state had not yet received Russell's request to release her husband's body.

He said arrangements must be made to release the body and once that happens a death certificate will be filed and the cause of death made public. He said it is too soon to speculate on when that might happen._______

BOSTON (AP) -- Boston police say three more suspects have been taken into custody in the marathon bombings.

In a tweet Wednesday morning, the police department says only that three more suspects are in custody and more details will follow. Police spokeswoman Cheryl Fiandaca confirmed the tweet but referred all other questions to the FBI.

Three people were killed and more than 260 injured on April 15 when two bombs exploded near the finish line.

Suspect Tamerlan Tsarnaev died after a gunfight with police several days later. His brother, Dzhokhar Tsarnaev, was captured and lies in a hospital prison.

Both are Russian natives who lived for several years in the U.S. They are accused of using a weapon of mass destruction.
